From the giant volcanic cone of Diamond Head to the historic lagoon of Pearl Harbor, Oahu offers endless rewards to those who visit. Visit Honolulu, Hawaii’s capital since the reign of King Kamehameha III, for bustling urban scenes, or do some sunbathing at Waimea Bay, Hanauma Bay or Sandy Beach. For a bit of island enlightenment, be sure to make a trip to the Polynesian Cultural Center.
